The insert positioning post 5-1 is located on the upper surface of the pre-assembly worktable 6, and the position of each insert positioning post 5-1 corresponds to the insert installation hole of the mold. The upper surface of each insert positioning post 5-1 is a conical surface, forming a guiding part. The pre-assembly worktable 6 is provided with the same number of positioning mounting blocks as the insert positioning mechanisms 5. The insert positioning posts 5-1 and the fourth detection sensor 5-2 are mounted on the positioning mounting blocks. In this specific embodiment: the pre-assembly worktable 6 is a rectangular worktable with 50 grooves and 50 insert positioning posts 5-1. The 50 grooves are distributed around the circumference of the pre-assembly worktable 6, corresponding to the installation positions of the mold inserts. Each groove contains a positioning block.

In this specific embodiment, each of the two initial insert gripping mechanisms is equipped with five first jaw gripping mechanisms 3-2. The first robotic arm 3-1 is equipped with a jaw turntable 3-4. Each first jaw gripping mechanism 3-2 is evenly distributed on the jaw turntable 3-4 via a first L-shaped mounting block 3-5. After the first jaw gripping mechanism 3-2 grips the insert, the second detection sensor 3-3 will detect and release a signal, and then rotate to the next gripper to grip it. 。 The first jaw gripping mechanism is an existing jaw gripping mechanism. Each of the first jaw gripping mechanisms 3-2 is provided with a second detection sensor 3-3. The second detection sensor 3-3 is installed on the first L-shaped mounting block. The second detection sensor is used to detect whether the first jaw gripping mechanism 3-2 has gripped the insert.

[0051] The secondary insert gripping mechanism 4 includes a second robotic arm and a transfer mounting plate 4-4 mounted on the second robotic arm. The second robotic arm is omitted from the accompanying drawings of this specific embodiment. Possibly, the transfer mounting plate 4-4 is mounted on the second robotic arm via a membrane. The transfer mounting plate 4-4 is provided with a plurality of second claw gripping mechanisms 4-3 and at least two positioning guide posts 4-5. The number and distribution of the plurality of second claw gripping mechanisms 4-3 correspond to the insert positioning mechanism 5 of the pre-assembly worktable 6, and are used to grip each insert on the pre-assembly worktable 6 and centrally transport them to the insert mounting position of the mold to be processed. Each of the second jaw gripping mechanisms 4-3 is equipped with a third detection sensor 4-1 and an ejection mechanism 4-2. The ejection mechanism 4-2 is used to eject the insert on the second jaw gripping mechanism 4-3. The third detection sensor 4-1 is used to detect whether the second jaw gripping mechanism 4-3 has gripped the insert. The transfer mounting plate 4-4 is equipped with the same number of second L-shaped mounting blocks 4-7 as the second jaw gripping mechanisms 4-3. The vertical section of the second L-shaped mounting block is a hollow structure. The second jaw gripping mechanism 4-3 is located on the horizontal section of the second L-shaped mounting block. The jaws of the second jaw gripping mechanism 4-3 are located at the upper end of the second L-shaped mounting block. The third detection sensor 4-1 is located on the vertical section of the second L-shaped mounting block. The ejection mechanism 4-2 is located at the lower end of the second L-shaped mounting block. The second jaw gripping mechanism 4-3 is an existing jaw gripping mechanism, and the ejection mechanism 4-2 is an existing ejector pin mechanism. The ejector pin ejects the insert through the hollow structure of the second L-shaped mounting block. In this specific embodiment: the transfer mounting plate 4-4 has 50 grooves, and 50 second L-shaped mounting blocks are bolted into the grooves of the transfer mounting plate 4-4, with the second L-shaped mounting blocks extending out of the grooves. 50 second jaw clamping mechanisms 4-3 are respectively disposed on the horizontal sections of the second L-shaped mounting blocks. 50 third detection sensors 4-1 are mounted on the upper ends of the second L-shaped mounting blocks, and the ejection mechanism 4-2 is mounted on the lower ends of the second L-shaped mounting blocks. The first jaw clamping mechanism, the second jaw clamping mechanism 4-3, and the ejection mechanism 4-2 are all driven by cylinders. Each positioning guide post 4-5 is mounted on the transfer mounting plate 4-4 via lugs. The positioning guide post 4-5 is used to cooperate with the guide positioning groove on the pre-assembly worktable 6 or the guide groove in the mold. When the transfer mounting plate 4-4 moves to the pre-assembly worktable 6, the positioning guide post 4-5 is inserted into the guide positioning groove and positioned to locate the positions of each second claw clamping mechanism 4-3 on the transfer mounting plate 4-4, facilitating the clamping of the insert. When the transfer mounting plate 4-4 places the clamped insert into the mold, the positioning guide post 4-5 is inserted into the guide groove and positioned to cooperate with the guide groove in the mold before the insert is released and placed into the mold. In this specific embodiment, four positioning guide posts 4-5 are provided.

[0052] The electrical components on the pre-assembly workbench 6, the clamping mechanism, and the automatic feeding mechanism are all electrically connected to the controller. The controller is a PLC controller, which controls the start and stop of the electrical components on the pre-assembly workbench 6, the clamping mechanism, and the automatic feeding mechanism, respectively.

[0053] In this specific embodiment: two automatic feeding mechanisms are provided, and both automatic feeding mechanisms are located on one side of the pre-assembled workbench 6. The automatic feeding mechanism includes a discharge worktable, a vibrating screen 1, an insert gripping and positioning platform 1-3, and a first detection sensor 1-4 mounted on the discharge worktable. The vibrating screen 1 is located on the side of the pre-assembly worktable 6 and is used to automatically screen and output inserts that meet the requirements for horizontal placement. The discharge end of the vibrating screen 1 is provided with the insert gripping and positioning platform 1-3. The lower end of the insert gripping and positioning platform 1-3 is mounted on the discharge worktable via a support base. The upper surface of the insert gripping and positioning platform 1-3 has an insert positioning groove and two insert clamping notches symmetrically arranged on both sides of the insert positioning groove. The side of the insert gripping and positioning platform 1-3 has a sensor detection hole, which is connected to the insert positioning groove. The first detection sensor 1-4 is mounted on the support base via a bracket. The detection part of the first detection sensor 1-4 is inserted into the sensor detection hole. The first detection sensor 1-4 detects whether there is an insert on the insert gripping and positioning platform 1-3. If a missing insert is detected, the equipment will report an error. In this specific embodiment: the vibrating screen 1 includes a vibrator, a vibrating disk 1-1, and a material guide rail 1-2. The vibrator is placed on the discharge workbench, and the vibrating disk 1-1 is set on the vibrator. The vibrating disk 1-1 is provided with a spiral channel. The discharge end of the spiral channel is provided with a material guide groove 1-5 for horizontal output of pre-installed inserts. The opening of the material guide groove 1-5 is set on the side to form a groove for accommodating the horizontally placed inserts. The height of the groove is greater than the height of the horizontally placed inserts and less than the height of the vertically placed inserts. The connection between the spiral channel and the guide trough 1-5 is provided with a transition platform 1-6. The upper end cover of the guide trough 1-5 gradually widens from the transition platform end, facilitating the entry of horizontally placed inserts into the guide trough. The upper end of the guide trough 1-5 is also provided with a rejection rod 1-7, which is an arc-shaped rod extending out of the guide trough 1-5. The rejection rod prevents vertically placed inserts from continuing to advance and falling into the vibrating plate 1-1, thereby filtering out inserts that meet the horizontal setting requirements. The outlet of the guide trough 1-5 is connected to the guide rail 1-2. The lower end of the guide rail 1-2 is mounted on the discharge workbench via a support frame. Possibly, a vertical vibrator is also provided on the upper surface of the guide rail 1-2.

[0054] It may also include an alarm device, which is electrically connected to the controller and is used to automatically alarm and prompt when abnormal situations such as missing or incorrect installation of equipment are detected.

[0055] Possibly, the controller is electrically connected to the mold's control system, automatically sending the detected signals to the mold's control system, thereby realizing the linkage between the pre-installation of the battery box cover insert, the error identification device, and the mold, improving the intelligence level of the equipment and increasing work efficiency.

[0056] Possibly, both the first jaw clamping mechanism 3-2 and the second jaw clamping mechanism 4-3 include jaws and a driving mechanism. Each jaw includes a connecting portion for connection to the driving mechanism and a clamping portion extending laterally from the connecting portion. The clamping end face of the clamping portion is provided with an arc surface for clamping the insert, making clamping more stable. The clamping portion of the jaw of the second jaw clamping mechanism 4-3 extends laterally and obliquely upward along the connecting portion of the jaw of the second jaw clamping mechanism 4-3, to make way for the ejector pins of the mold when the insert is placed in the mold. The clamping portion of the jaw of the first jaw clamping mechanism 3-2 extends laterally horizontally along the connecting portion of the jaw of the first jaw clamping mechanism.

[0057] Possibly, the transfer mounting plate 4-4 has a weight reduction hole in the middle, a second claw clamping mechanism 4-3 is provided on the front of the transfer mounting plate 4-4, and at least two vacuum suction cups for adsorbing the processed battery box cover are provided on the back. The vacuum suction cups are connected to a compressed air source through pipes. The processed workpieces on the mold are automatically removed by the vacuum suction cups 4-6, which improves the level of intelligence and work efficiency.

[0058] The working principle of this utility model:

[0059] First, a manual operator places the circular insert 2 into the vibrating screen 11 of the automatic feeding mechanism. The vibration force generated in the vibrating screen 11 pushes the circular insert 2 onto the guide rail 1-2, where it moves to the insert gripping and positioning platform 1-3. The platform 1-3 restricts the circular insert 2 from moving forward. Two robotic arms 3 rotate to the front end of the platform 1-3 and use the first jaw gripping mechanism of the two first insert gripping mechanisms to rotate and grip the circular insert 2. After gripping one circular insert 2, the first jaw gripping mechanism automatically rotates to grip the next circular insert 2 until all five first jaw gripping mechanisms 2 have gripped the insert. During the gripping process, the first sensor 1-4 at the front end of the insert gripping and positioning platform 1-3 continuously monitors the process. If a missed grip is detected, the equipment will report an error and stop operating.

[0060] Secondly, after the initial insert gripping mechanism grasps the insert, the first robotic arm 3-1 rotates to the insert positioning post 5-1 of the insert positioning mechanism 5, precisely aligning with the insert positioning post 5-1, and sequentially placing each circular insert 2 into the insert positioning post 5-1. Each of the two initial insert gripping mechanisms is responsible for gripping and placing half of the circular inserts 2. Once the initial insert gripping mechanism has placed all the inserts on the pre-assembly worktable 6 into position on the insert positioning post 5-1, the fourth detection sensor next to the insert positioning post 5-1 will perform a mis-installation detection on the circular inserts 2. If a mis-installation or omission of a circular insert 2 is detected, the device will report an error and stop operating.

[0061] Then, after the inspection is completed without error, the second robotic arm of the secondary insert clamping mechanism 4 rotates the transfer mounting plate 4-4 to the guide positioning groove. The positioning guide post 4-5 cooperates with the guide positioning groove to ensure that the second claw clamping mechanism 4-3 grasps the plate accurately. The second robotic arm moves the transfer mounting plate 4-4 into the mold, and the positioning guide post 4-5 is precisely positioned by cooperating with the guide groove of the mold. The second claw clamping mechanism 4-3 delivers all the inserts on the pre-installation worktable 6 to the insert pre-installation position of the mold in one go, which improves work efficiency and avoids errors caused by manual operation and personnel safety issues.

[0062] Finally, after the battery box cover is injection molded, the secondary insert clamping mechanism 4 will rotate into the mold to remove the part. During removal, the vacuum suction cup 4-6 at the lower end of the transfer mounting plate 4-4 of the secondary insert clamping mechanism 4 will clamp the workpiece and then pick it up and place it on the platform.

[0063] This invention not only accurately identifies insert pre-assembly and misassembly errors, significantly improving material utilization and production efficiency, and reducing product omission rates, thus effectively controlling production costs and product quality, but also allows for flexible replacement of different pre-assembly films to identify different inserts, improving the equipment's versatility.
